Application
YH metallurgical hoist is installed on the I beam to lift weights. And it can travel straight and curvedly., which ensures safety. It is forbidden to use in such dangerous operating as easily combustible, explosive, corrosive, etc. It can be applied to lift molten metal.
Technical characteristics
1 YH metallurgical electric hoist consists of several detached parts that are lifting mechanism, traveling mechanism, controlling devices and braking devices, which makes it easy to inspect and repair.
2 The motor adopts three-phrase asynchronous motors, whose protection class IP44, and insulation class H.
3 High temperature insulation device is installed under the hoist, which avoids direct thermal radiation.
4 Wire rope adopts steel cored wire rope which is thermostable.
5 Lifting mechanism is equipped with overload limiter. When the weight exceeds 95% of rated lifting capacity, the limiter signals; when weight reaches 105% of rated lifting capacity, lifting circuit is broken, and lifting contactor releases, and then the motor stops rotating without power.
6 Lifting mechanism has two protection of lifting limitation. The first is fire cutoff protection, and the second is controlling cutoff protection.
